I agree, that is what is happening here.
I think this is invalid, so I am closing it.

--- Comment #4 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
It should be possible to create a suppression file to silence false positives:
http://valgrind.org/docs/manual/manual-core.html#manual-core.suppress

but a comment in the code search_line_sse2 (lex.c:372) is probably as good to
avoid further duplicates.

I think that's by design (it won't cross page boundary though).
